Tool suggestion for tracking CPU and Memory usage of a running code

Dear all,

I am running a CoAP Java Implementation and I need to get CPU usage and the memory usage of the code that I run. Is there any tool for tracking the specific test code ?

* here is the test I would like to track : https://github.com/joakimb/OSCoAP/tree/master/californium-core/src/test/java/org/eclipse/californium/core/test/objectsecurity

Thanks in advance...
